MACHINE FOR WINDING QUILLS AND BOBBINS.

SPECIFICATION forming part of Letters Patent No. 385,480, dated July 3, 1888.

Application filed June 25, 1886.

T whom, it may concern:

Be it known that I, VERNON RoYLn, of Paterson, in the county of lassaio and State of New Jersey, have invented a new and useful Improvement in Machines for \Vinding Quills and Bobbins, of which the following is a specification.

Although my invention, or certain features thereof, may be employed in winding quills, spools, and bobbins for various purposes, the invention as a whole is more particularly intended for winding shuttle-quills with silk, and the invention will be described as embodied in a machine for that purpose.

Shuttle-quills for silk-weaving are com monly wound in taper or conical layers with a quick traverse in one direction and a slower return traverse to bind and securely hold the silk thread in place; and as the quills are built up layer by layer it becomes necessary to change the relation of the spindle and traverse mechanism or to produce the feed of the spindle.

My invention consists in novel combinations of parts, hereinafter described, and pointed out in' the claims, whereby the feed of the spindle is produced as the winding of the quill progresses, and which comprise a spin dle held by frictional engagement of smooth and toothless surfaces in a clutch which has a regular and predetermined reciprocating movement and a fixed abutment at the end of the spindle, against which the body of thread on the quill or bobbin will strike at the termination of the traverse movement in one direction. As each layer is wound, the increased size or height of the body of thread on the quill or bobbin causes it to strike against the abutment, and the spindle is pushed or fed through the friction-clutch a distance corresponding to the thickness of the layer. By this means the feed automatically proportions itself to the uneven size and varying diameter of the silk thread-a result which, I. believe, has not before been accomplished.

The invention also consists in novel combinations of parts, also hereinafter described, and pointed out in the claims, whereby the spindle and friction-clutch are properly guided in their reciprocating movements, and the flier, whirl, and abutment for the quill or bob- Serial No. 206,194. (No model.)

bin supported in proper relative position, such combinations including a fixed tube, concentrio with and outside of which are arranged the flier, whirl, and clutch, and within which is fitted the spindle; and the spindle,being tubular, receives within it a fixed central rod suppoi-ting at its end and beyond the end of the spindle a cup-shaped abutment,into which the quill or bobbin is carried by the traverse.

The invention also consists in novel combinations of parts, hereinafter described, and pointed out in the claims, whereby I provide a simple and effective stop-motion, through which the whirl will be automatically thrown off to stop the flier on the breaking of a thread or when a quill or bobbin is full, or, ifdcsircd, by hand.

In winding a quill the length of the traverse or number of turns of thread should vary both in the layers wound with quick traverse and in the layers wound with slow traverse, and the traverse should terminate at different points to give a roundness of profile alternately at the ends of the traverse. This is accomplished by necessity in winding by hand, because of the impossibility of terminating the traverse with uniform regularity in the different layers; butin automatic quilling-i'nachines the result has not heretofore been accomplished.

The invention also consists in other novel combinations of parts including a single cam, preferably of a simple and novel construction, hereinafter described, and pointed out in the claims, whereby the quills 'on opposite sides of a machine are traversed in a manner to produce the results above described.

The invention also consists in novel combinations, also 11 ereinaf ter described,and pointed out in the claims, in a machine which has spindles on opposite sides of the frame driven by a single band which in passing between the spindles in one direction encircles a pulley, whereby the band on the opposite spindles in the machine may, on stopping work, be slack ened by simply turning the band-driving shaft a portion of a turn in a backward direction; also including a chuck of novel construction, whereby the quill may be hold fast on the end of the spindle.

In the accompanying drawings, Figure 1 represents an elevation, partly in end view and partly in transverse section, of a qnilling-inachine embodying my invention. Fig. 2 is a side view thereof, all the spindle and other parts which are many times duplicated not being shown.

Fig. 19 is an elevation of some ofthe parts which are shown in Fig. 18, illustrating the stop-motion in a different position. Fig. 20 is an elevation at right angles to Fig. 18 of parts shown therein. Fig. 21 is a plan of parts shown in Figs. 18, 19, and 20,- and Fig. 22 illustrates the development of a traverse-cam shown in the last said figures.

Similar letters of reference designate corresponding parts in all the figures.

A designates the two upright end frames of the machine, which are united by suitable cross bars or rails, AKA], and by cross stretchers A. and A, which may be of wood. The cross rails or stretchers A support the pins or fixed spindles b for the spools or bobbins b, from which the thread is taken for winding the quills, and the cross-rails or stretcher-s A, which are or may be of wood, support brackets B, by which the several spindles and their appurtenances are supported.

Along opposite sides of the machine are arranged two series of brackets, 13, supporting two rows or tiers of spindles, and a description of one spindle and its appurtenances applies to all of them. The construction and relative arrangement ofthe spindle and its appnr tenances are best shown in Figs. 3 to 10, in elusive, to which I shall now refer.

Each bracket B is constructed with an upwardly projecting cylindric hub, b upon which rotates freely the whirl b, and which is constructed to form a shoulder and adjacent oil-cup, b, as best shown in Fig. 3. The hub b is bored out,so as to form a cylindric socket, Within which an upright tube, If, is held in fixed position by aset-screw, I), as shown in Fig. 4, or by other suitable means. The fixed tube 1) projects above the whirl Z)",'and upon the upwardly-projecting portion of this tube the hub b of the flier b rotates freely. The upper portion of the flier b is provided with an oblique slot, 1), as shown in Fig. 8, which provides for the ready introduction of thread. The whirl I) is capable of rising and falling slightly upon the hub If, and has a clutchconneetion with the flierhub b As here represented, this clutch-connection is formed by a lug or projection, N on the whirl,which, when the whirl is raised, engages a corresponding lug or projection, I), on the flierhub, and so transmits rotary motion to the flier. WVhen the whirl b is lowered, as shown in Fig. 3, so that its lug or projection b ranges below the lug or projection I) on the flier, the flier will be stopped. The position of the whirl b is controlled by a shipper, which con sists of a fork, b, embracing a groove in the whirl and mounted upon an upright stein, I), which slides upward and downward in the bracket B.

G designates the spindle, which is tubular and non-rotary and which is fitted to slide freely upward and downward within the fixed tube This spindle O has upon its upper end a chuck or clutch, G, which comprises spring-actuated jaws 0, adapted to engage a circumferential groove, 0, in the lower end or head of a quill, C and which also has a tooth or projection, c", for engaginga notch, c, in the quill-head. By this means the quill G is secured upon the upper end of the spindle, so that it will rise and fall with the-spindle.

If the circumferential grooves c in all the quills employed are atuniform distances from the ends of the quills, the chuck above described will well answcr the purpose; but as the quills often vary in this particular I may employ a chuck of the form shown in Figs. 8, 8", 8, and. 8, to which I now refer. In those figures the spindle C has a head or chuck body, 0, which has projections or ribs 0 for entering notches c in the head of the quill G", and the quill is held in place by a semicircular keeper, m, which may be made of wire, and has a downwardly-projecting and screwthreaded stem or shank, m, adjustable in the chuck-body O to bring said keeper to exactly the right height for engaging the groove 0 in the quill. The cup-shaped abutment 0, hereinat'ter described, is necessarily removed each time a quill is to be placed on thespindle, and if it be desired to adjust the keeper m to bring it to proper position a stop-gage, F which is clamped on the lower end of the spindle, as hereinafter described, may be removed, and by taking hold of a finger-piece, n, on the chuck body the spindle may be raised above a stationary rod, Cflwhich is within it, and the keeper adjusted, as desired. The chuck-body 0 also has a projectiomn, which serves as a rest for the thumb or fingers in springing the keeper m into the groove 0 of a quill.

\Vithin and concentric with the tubular spindle O is a fixed or stationary red, O", which extends entirely through the spindle O and projects above and below the same. At its upper end, and above the spindle, the red 0 supports an abutment, C, which ishere shown as of invcrted-cup shape and arranged concentric with the spindle O and the quill G". In order to remove the quill G and replace it by a fresh quill it is necessary to remove the abutment G, and I therefore secure the abutment detachably in place on the stationary red C by means best shown in Figs. 3, 4, 6, and 7. The upper end of the stationary rod 0 is grooved circumferentially at c, and is cut away or recessed above the groove and on one side of the rod to the depth of the groove, as shown at c. Projecting from the rod in the line of the circumferential groove 0 is a pin, 0, and projecting inward from the abutment C is a pin, 0. In order to place the cupshaped abutment 0' upon the rod C",thc pin 0 is brought to the recessed side 0 of the rod, and the abutment is then slipped down until the pin 0 reaches the plane of the groove 0 after which the abutment is turned slightly until the pin c strikes the pin or shoulder a. This forms a very secure lock for holding the abutment 0 upon the red O in such manner that it may be readily detached therefrom whenever it is desired to replace a wound quill with a fresh or unwound quill.

Thecup'shapedabutment,oranyotherequivalent abutment against which the body of thread on the quill may strike, is intended for usein connection with aspindle which is traversed upward and downward by aclutch which is in frictional engagement with it.

D designates a clutch sleeve or bushing, which is shown in sectional view in Figs. 3, 16, and 1G, and which is fitted to slide freely upon the exterior of the fixed tube b and engages with said tube by smooth and toothless surfaces, so as to provide for a very slight move ment of theclutch upon said tube. XVithin the portion covered by the movement of the clutch'sleeve D the fixed tube b is slotted at opposite sides, as shown best at d in Fig. 16, and sliding transversely within the opposite sides of the clutch-sleeve D are clutch-jaws d, which project through the slots cl in the fixed tube If and bear with frictional contact upon opposite sides of the spindle O, as best shown in Figs. 16 and 16. These clutch-jaws d are pressed inward by levers d fulcrumed at d" to the clutch-sleeve D, and actuated by a spring, (1", in order to press them with the requisite. force against the spindle 0. As shown in Fig. 16, the arms of the levers (2' with which the spring (I engages, are notched at different points in their length, so as to provide for setting the spring to exert more or less pressure of the clutclrjaws cl upon the spindle O.

From the above description it will be seen that normally the reciprocating or traversing movement of the friction-clutch D will impart a like traversing movement to the spindle U, which it holds by frictional engagement, and if any unusual resistance be opposed to the upward movement of the spindle the hold of the clutch upon the spindle will yield slightly, and the clutch will complete its upward movement,while the spindle will be held down and pushed slightly through the clutch. This is exactly the office performed by the cupshaped abutment G, into which the conical body of thread upon the quill enters at the termination of the traversing movement of the spindle in one direction. The thread is wound in conical layers upon the quill, and as the body of the thread is increased by a double layer at each upward and downward traverse of the spindle, the body of thread will at the end of each upward traverse strike the cup-shaped abutment O, and will thus push or feed the spindle slightly downward through the clutch D. This combination, with a fixed abut-ment above the spindle, of a tavcrsing clutch in which the spindle is held by friction, and by which the spindle is traversed, is a very desirable arrangement, because by it the feed of the spindle will be exactly proportioned to the degree of fineness of the thread being wound.

The traversing motion ofthefriction-clutches D, which are on opposite sides of the machine, is produced by two rockshall's, 1), extending lengthwise of the machine and provided with arms D", each engaging a clutch, D, as best shown in Fig. 3. These two rock-shalts are operated from a single cam, E, which will be particnlarl y hereinafter described, and which acts upon a lever, E, fnlcrumed at e, and conneeted bya rod, 6, with an arm, 6 extending downward from the rock-shaft D on one side ofthe machine, and by a rod, c", with an arm, 0*, extending upward from the rockshaft D on the other side of the machine, The bear- This lever E is held against the cam by a spring, 0 which is connected by an arm, 0, upon one of the rock-shafts D, and it will be understood that by this mechanism all the spindles O on opposite sides of the machine are traversed upward and downward in unison.

Each spindle and flier is provided with a stop-motion,whereby the whirl may be thrown off from the flier and the rotation of the flier stopped, either when the thread breaks or when a quill becomes full, or, if desired, by hand, the stoppage of the ilier being accomplished through the same set of stop mechanism in either case. As I have before stated, the shipper I), controlling each whirl If, is upon thestem I), which slides vertically within a suitable socket in a bracket, B, and which, when not held up, is depressed or slid downward by a spring, 6 applied to the stem I), as shown in Fig. 3. The stop-motion for each spindle comprises a stopdever, F, which is pivoted or fulcrumed at], and which is preferably of U shape or forked, as best shown in Fig. 17, so as to embracethe bracket B. Thislever has atail-piece,f', which serves as ahandle wherebyit maybe moved by hand. The stoplever F has at one side an arm, f, to which is pivoted or otherwise attached a rod,f, having ashoulder, f", and it also has at opposite sides arms/' which are connected by rods or depending links with a collar, f fast upon the lower end of the shipper-stem b, and also forming a shoulder for the spring c to bear against. In Fig. 3 the whirl is shown as thrown off the flier, and the shipper b is inits lowermost position. By swinging the stop-lever F upward from the position shown in Fig. 3 to the position shown in Fig. 4, the pivotal point of attachment of the rodf to the leverarm f will be carried past a straight line drawn through the fulcrum f and the point of attachment of the rod orliuk f to the stem 1) of the shipper, and consequently when the stop-lever is placed or set by hand in the position shown in Fig. 4 the shipper I) will remain in its elevated position and maintain the whirl operative until said lever is thrown off by the breaking of the thread by a quill becoming full or by hand.

I will first describe how the lever F and the whirl b are thrown off on the breaking of the thread. I have in Fig. 1, and also in Fig. 2, shown taller-wires or t'allersf which are pivoted at f, and through which the threads 8 are severally conducted on their way to the fliers b The tail of each faller f which projects on the opposite side of the pivot/' from the thread-eye, is connected by a cord or wire, f, with the shouldered rod f, pertaining to a spindle. So long as the thread remains intact the taller will be maintained in the elevated position and the shouldered rod f will remain below the reach of a reciprocating or oscillating knoeker, G, having a constant to and-fro reciprocating or oscillating motion. The faller f instead of acting by its weight on a balanced bar or beam on which it falls, as

is usual, serves by an upward pull on the wire or cordf, when a thread breaks, to move the shouldered rodf within reach of the knocker G, and at its next movement the knocker strikes the shoulderf and by pulling upon the shouldered rod and the arm f" of the stop lever F swings said stop-lever from the position shown in Figs. 4 and 10 to the position shown in Figs. 3 and 9, thereby releasing the shipper-fork b and permitting the spring 6 to throw the shipper and whirl downward out of driving connection with the hub I) of the The knocker-arms G, which pertain to the spindles on opposite sides of the machine, extend from two roekshafts, G, arranged on opposite sides of the machine, and these rockshafts have motion imparted to them in this example of my invention by a single eccentric, f", which transmits motion through two rods, f, to arms f extending upward from the rock-shafts G, as best shown in Fig. 1.

H designates the main driving-shaft of the machine, to which motion may be imparted by a belt running over fast and loose pulleys h h, and which, by means of a pinion, h, and awheel, 7f, transmits rotary motion to the eccentric f. The wheel h and the eccentric f may be formed in the same piece or connected to rotate as one, and they turn upon a stud, h, projecting inward from the end frame, A, of the machine, as shown in Fig. 2. The rock-shaft G and the k nockcrarms G are reciprocated or oscillated constantly and without effect until such time as a thread breaks and one of the shouldered rodsf is lifted within reach of the knocker-arm G, whereupon the flier of a corresponding spindle is stopped until the break is repaired and the stoplever F reset.

The throwing off of the whirl b when a quill becomes full is effected by mechanism which I will now describe, and which acts through the same pivoted stop-lever, F. At one side the pivoted stop-lever F is prolonged to form an arm, h, from which depends a rod, F, provided with a shoulder, h, and having, prefer ably, a pointed extremity, h To the lower end of the fixed tube 12 is secured a yoke or hanger, D which serves to support the inner stationary rod, 0 on which the spindle 0 slides, and which also serves to guide and prevent the turning of the stop-gage F which is adj ustably secured to the lower end of the spi ndle O. Thisstop-gage F has a fork or notch, 71?, (best shown in Fig. 5,) whereby it is guided upon the yoke or hanger D and it is divided or split at h, so that by means of a clamping or binding screw, it it may be tightly clamped upon the lower end of the spindle O. The stop-gage F has a laterallyprojecting arm, h, against which the depending rod F rests, and at the end of that arm is a lip or shoulder, h", which prevents the rod F from slipping off laterally beyond the end of said arm h. The back of the arm h is beveled from its upper edge downward and rearward, as shown at h in Fig. 5, and this beveled back of said arm combines with the pointed extremity of the depending rod F in a way soon to be described. The clutch-sleeve D has a lateral projection,spur, or pin, h,which is'best shown in Figs. 9 and 10, and which as the clutch moves upward will strike against the shoulder h of the depending rod F, if such shoulder is within range of the path traveled by said projection or pin. The bearing which is afforded by the arm it of the stop-gage to the depending rod F prevents said rod from swinging inward to bring its shoulder h in the path of the projection h so long as the stop-gage F does not travel below the point of the rod F. Ihave before described that as the winding progresses the spindle, and therefore the stopgagc F, are pushed downward step by step through the friction-clutch I) by the action of the quill on the fixed abutment C, and the parts are so adj ustcd for operation that when a quill is full the adjustable stop-gage F will at the lower termination of the traverse of the spindle just clear the point of the depending rod F. When this occurs, the rod, being offset slightly at its upper portion, asshown best in Figs. 9 and 10, will swing inward sufficiently to carry its shoulder it within range of the stop projection it on the friction-clutch D, and at the next upward movement of the friction-clutch said projection, acting upon the shoulder of the rod F, will push the rod upward ant swing the stop-lever F from the position shown in Figs. 4 and 10 to the position shown in Figs. 3 and 9, thereby permitting the spring 0 to throw down the shipper Z)" and to throw off the whirl b from the flier. It is advantageous to have the back of the arm it formed with an incline, h, so that in case the rod F does not swing inward sufficiently to bring its shoulder it within range of the stop projection h the inclined arm will, at the next upward movement of the spindle, act upon the extremity of the rod F to force it inward to bring its shoulder it within range of the stop projection h.

The stopmotion which I have above described, and which operates under the three conditions named, is not likely to get out of order, is comparatively simple, and is certain in its operation. As best shown in Fig. 3, the lower end of the rod 0 is threaded and adj ustably secured by nuts in the yoke or hanger D. This ad justmcnt provides for varying the height of the abutment G to suit variations in the conical portions of the different quills.

I will now describe the cam E, prcmising that this cam or any other single cam capable of producing like results and comprising like elements constitutes an important feature of my invention. The cam, E, here shown, and which serves to impart traverse to all the spindles on both sides of the machine, is a facecam operating upon a knife-edged piece or projection, upon the lever E. This cam is upon a cross'shaft, i, which receives motion through a worm and worm-wheel, t t", and

pinions or toothed wheels i i" from the main shaft H. The bearing-surface of the cam presents a succession of long and short inclines, i i, which are arranged alternately on the circumference of the cam and which are oblique to the plane of rotation of the cam. Neither the long inclines nor the short inclines are of uniform length, but vary each among themselves or respectively to each other, as clearly seen by the dotted lines in Fig. 15, which are uniformly spaced. These inclines throughout their series or succession are arranged alternately, so as to produce alternately the quick and slow traverse required in winding quills, the short inclines corresponding to the quick traverse and the longer inclines corresponding to the slow traverse. Because of its peculiarity of construction the cam Fl not only produces alternately a quick and a slow traverse, but the number of turns of thread in the several layers wound with quick traverse will vary, as will also the number of turns in the layers wound with slow traverse. The cam also is constructed so as to terminate the traverse at different points at the top and bottom of the layers of thread upon the quill, and so acts to produce a convex profile at the lower termination of the conical winding, thereby tightening the thread of one layer upon another and holding the thread securely, with its long and short traverse preserved. This latter effect is produced by terminating the inclines t of the cam in different planes or paths, as is bestunderstood from the diagram Fig. 15. These inclines 2', although they terminate their throw in different planes or paths, have a substantially uniform extent of throw. In Fig. 15 the twodotted lines 1 73 indicate the extreme points of travel reached by any of the inclines. It will here be seen that while certain of the inclines terminate upon the dotted line i as shown at i, such inclines at their opposite ends fall considerably short of the dotted line i and in like manner those inclines which terminate at the dotted line f, as at i fall considerably short at opposite ends of the line '5 This drunkenness of the cam serves to terminate the traversein the different layers of the quill at different points, and accomplishes in a very simple way what has before required much more complicated mechanism.

1 will now describe how the whirls I) in the two rows at opposite sides of the machine are driven, the arrangement of a drivingband relatively to a driving-pulley and two whirls at opposite sides of the machine being best shown in Figs. 11 and 12. Upon the main driving-shaft H are flanged driving-pulleys H, corresponding in number to the whirls on one side of the machine, and each band I is of a length to encircle two whirls, b, on opposite sides of the machine, and to also encircle in its travel between the whirls in one direc tion the driving-pulley H. The whirls b",

which are driven by the band I, are offset in opposite directions laterally from the plane of IIO the driving-pulley II, as shown in Fig. 12, in order to prevent the portion of band running onto the driving-pulley from interfering with the portion of band running off from or leaving the driving-pulley. In order to prevent those portions of the band from interfering with that portion running directly between the whirls If", the driving-pulley H is raised slightly above the level of the whirls. To still further prevent the portion of band running onto the driving-pulley H from interfering with the portion of band leaving said pulley, the face of the pulley is slightly conical, as shown in Fig. 12, and by turning the driving-shaft H a portion of a turn backward the band will be run down onto the smaller side of the driving-pulley II and thereby slackened. In the use of quilling-machines the bands are often thrown oii' when stopping the machine in order that they shall not be strained by being left under tension; but when conical driving-pulleys II are employed the same result of slackening the bands is secured by turning the shaftH and driving-pulleys backward a trifle and without throwing off the bands from their pulleys.

In Figs. 18 to 22 I have shown a modification of my invention in which an independent traverse-cam is employed for each spindle and in which each spindle has an independentlyoperated reciprocating or oscillating knockerarm, G. In these figures, also, I have illustrated a very slight modification of the stopmotion, which consists, simply, in dispensing with the rods or links f, before described, and providing on the shipper b" a reverse incline,j, upon which the arm f of the stoplever F acts to lift the shipper in order to throw in the whirl N. In Fig. 18 the stop-motion is shown in the position which it occupies when the whirl is thrown off the flier, and in Fig. 19 the parts are shown in the position which they occupy when the whirl is raised and is operative to drive the flier. In order to set the whirl for work, the lever F is raised into the position shown in Fig. 19, and as its arm passes the apex of the double inclines j said lever will be held against accidental falling and will hold the shipper and whirl in their elevated position. A pull upon theshouldered rod f will, however, swing the lever F into the position shown in Fig. 18 and permit the spring 0 to throw off the whirl. In this modification of my invention the traverse-cam E is upon an upright shaft, J, which has a suitable bearing provided on the bracket B, and this cam engages a lateral projection, j, on the friction-clutch D, which reciprocates or traverses the spindle O. This cam therefore acts only to give the traverse movement in one direction, and. the friction-clutch D and spindle are returned or pulled downward by a spring, j as shown in Fig. 18. In this exam ple of the invention the hub b of the flier is provided with a worm or screw, 7' which engages a bevel-wheel, upon a cross-shaft, j and this cross-shaft, by bevel-wheelsj j, trans inits motion to the upright shalt J, on which is the traversecam E. The crossshaft 7' here serves to reciprocate or oscillate the knocker-arm G through a rod, j worked from a erank-pimj, in the bevel-wheel j, and in this case the rocker-arm G is formed by a bell' crank lever pivoted at From the diagram, Fig. 22, it will be seen that the cam E is constructed like that before described,whieh is employed to operate all the spindles, in that it has the long and short inclines i, and in that the inclines terminate in different paths or planes of rotation.

The dotted lines 2' 2'' represent the extremes of throw of the inclines i in opposite directions, and where the inclines terminate nearest the dotted line 6 they fall farthest short of the dotted line i and vice versa.

hat I claim as my invention, and desire to secure by Letters Patent, is-
